[0/4] RTL9300 MDIO driver

Message

This series adds a driver for the MDIO controller on the RTL9300 family
of devices. The controller is a little unique in that we can't access
the SMI interfaces directly. Instead we associate the SMI interface with
a switch port and use the port number to address the SMI bus in
software.
